The SCS60 shaft collar is the definitive model in the SCS series — engineered for the 60 mm shaft diameter that serves the largest industrial drive systems, primary reduction gear outputs, and marine propulsion auxiliary drives. With an outer diameter of 95 mm, a 22 mm face width, an M10 clamping screw, and an 18 mm keyway — the widest in the entire series — the SCS60 represents the maximum retention capability achievable in a single-split aluminium shaft collar.
The 18 mm keyway (DIN 6885A 18×11, available to order) pairs with the 18×11 parallel key standard used on the output flanges of large industrial gearboxes, heavy ship winch drives, and large-scale material handling equipment. The SCS60 is a structural drive component that happens to offer the repositionability of a split-clamp collar.

🎉 Series Flagship — Maximum Capability
60mm bore, 95mm OD, M10 screw, 18mm keyway: the highest-performance single-split aluminium collar EP produces.
⚙ 18mm Keyway: Maximum Torque Transmission
DIN 6885A 18×11 key — serves the output shafts of 7.5kW–30kW gearboxes without any shaft modification or warranty concerns.
🛠 3mm Slit, 60mm One-Person Install
Even at 60mm bore, the 3mm slit allows tool-free collar installation over a fully assembled shaft in the field.
🌎 Marine and Outdoor Grade
Aluminium construction resists atmospheric and marine-environment corrosion; anodised finish available for salt-spray exposure.
60 mm is the output shaft diameter of industrial gearboxes in the 7.5–30 kW range from most major gearbox manufacturers. An SCS60 with 18 mm keyway at the output coupling retains the coupling flange against the full rated gearbox output torque and any axial thrust component, without requiring a machined shaft shoulder or circlip groove.
Marine deck machinery — cargo winches, anchor windlasses, and mooring capstans — runs primary drive shafts at 60 mm in the medium duty class. The SCS60's aluminium construction provides inherent corrosion resistance in the salt-spray marine environment, while the 18 mm keyway handles the high starting torques of machinery moving heavy anchor chains and mooring lines.
Centrifugal pump impellers and industrial fan wheels on 60 mm shafts require precise axial positioning relative to the volute or fan housing to achieve design efficiency. The SCS60 allows this axial position to be set and locked repeatably during commissioning, and reset quickly after impeller or wheel replacement without removing the motor or drive.
The 95 mm OD with 60 mm bore provides 17.5 mm of wall per side — identical to the SCS50's wall section, deliberately maintained despite the bore growing by 10 mm. The 3 mm slit is retained from the SCS50, enabling the same one-person, tool-free installation advantage on a 60 mm shaft. For applications where the SCS60 must serve as a precision axial datum — such as a heavy turbine shaft bearing preload reference — EP can supply the collar with a precision-ground face and bore, certified to ISO 286 tolerance grades. Contact the EP engineering team early in your project for precision-grade options.
The SCS60 is the largest standard catalogue model. For bore sizes above 60 mm, EP produces custom split-clamp collars to customer drawings — contact the engineering team with your bore diameter, OD envelope, face width, and torque requirements for a custom quotation.
The DIN 6885A 18×11 parallel key on a 60 mm shaft with a hub engagement length of 60 mm has a theoretical shear-area torque capacity well in excess of 1,000 N·m in steel. Actual safe working torque depends on key material, fit tolerance, and application service factor — EP can provide a specific torque calculation for your hub geometry.
Yes. Material test certificates (EN 10204 3.1 or 3.2) for the aluminium alloy can be provided on request for applications requiring documented material traceability — common in pressure equipment, marine, and nuclear auxiliary system specifications.
Available surface treatments include: standard anodising (10–15 μm), hard anodising (25–50 μm), and chromate conversion coating. Specify at order time via the contacts page.
